The gravitational force of attraction between a satellite and the earth gives rise to ______.

The correct answer is option 3 i.e. centripetal force The gravitational force of attraction between a satellite and the earth gives rise to centripetal force.Earth satellites are objects which revolve around the earth.Their motion is very similar to the motion of planets around the Sun and hence Kepler’s laws of planetary motion are equally applicable to them.In particular, their orbits around the earth are circular or elliptic.The artificial satellites orbiting the Earth remain in their orbits and do not fall down DUE to the attraction of the Earth (GRAVITY) which provides the necessary centripetal acceleration.We will consider a satellite in a circular orbit of a distance (R + H) from the centre of the earth, where R = radius of the earth.If m is the mass of the satellite and V its speed, the centripetal force required for this orbit is:\(F\left( {centripetal\;force} \right)\; = \;\frac{{m{V^2}}}{{R\; + \;h}}\), directed towards the centre.This centripetal force is provided by the gravitational force, which is: \(F\left( {gravitational\;force} \right)\; = \;\frac{{GmM}}{{R\; + \;h}}\), where M is the mass of the earth.Centripetal force: A force that acts on a body moving in a circular path and is directed towards the centre around which the body is moving.This force is applied to the OBJECT from outside and for this REASON, the centripetal force is an external force.It always acts towards the centre(so we do not assume that it is an internal force) but it is an external force.
